We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).

Boolean built-in type.

<description>

Boolean is a built-in type. There are two boolean values: [code]true[/code] and [code]false[/code]. You can think of it as a switch with on or off (1 or 0) setting. Booleans are used in programming for logic in condition statements, like [code]if[/code] statements.
|
|
Booleans can be directly used in [code]if[/code] statements. The code below demonstrates this on the [code]if can_shoot:[/code] line. You don't need to use [code]== true[/code], you only need [code]if can_shoot:[/code]. Similarly, use [code]if not can_shoot:[/code] rather than [code]== false[/code].
|
|
[codeblock]
|
|
var can_shoot = true
|
|
|
|
func shoot():
|
|
if can_shoot:
|
|
pass # Perform shooting actions here.
|
|
[/codeblock]
|
|
The following code will only create a bullet if both conditions are met: action "shoot" is pressed and if [code]can_shoot[/code] is [code]true[/code].
|
|
[b]Note:[/b] [code]Input.is_action_pressed("shoot")[/code] is also a boolean that is [code]true[/code] when "shoot" is pressed and [code]false[/code] when "shoot" isn't pressed.
|
|
[codeblock]
|
|
var can_shoot = true
|
|
|
|
func shoot():
|
|
if can_shoot and Input.is_action_pressed("shoot"):
|
|
create_bullet()
|
|
[/codeblock]
|
|
The following code will set [code]can_shoot[/code] to [code]false[/code] and start a timer. This will prevent player from shooting until the timer runs out. Next [code]can_shoot[/code] will be set to [code]true[/code] again allowing player to shoot once again.
|
|
[codeblock]
|
|
var can_shoot = true
|
|
onready var cool_down = $CoolDownTimer
|
|
|
|
func shoot():
|
|
if can_shoot and Input.is_action_pressed("shoot"):
|
|
create_bullet()
|
|
can_shoot = false
|
|
cool_down.start()
|
|
|
|
func _on_CoolDownTimer_timeout():
|
|
can_shoot = true
|
|
[/codeblock]

Cast a [String] value to a boolean value, this method will return [code]false[/code] if [code]""[/code] is passed in, and [code]true[/code] for all non-empty strings.
|
|
Examples: [code]bool("False")[/code] returns [code]true[/code], [code]bool("")[/code] returns [code]false[/code].
